Dear Pokhton, what is Your issue on the Sikhs leaving the historical conflicts?
From my experience they are quiet serious people, and evn in good relations to Afghans. I have often met Sikh people helping Afghans in economic problems in an admirable way.
Also I have noticed from my experience that Sikhs were quiet more friendly towards Muslims than followers of other faiths(except Islam) spread throughout India. Maybe it is a casual exoerience as I talk from what I saw in Europe.
